Southern Appalachian Raptor Research (SARR) conducts raptor trapping and banding at Big Bald Banding Station (BBBS) each autumn. The raptor set operates from 10:00 until 1-2 hours before sunset, from the first week in September to mid-November. Migrating raptors are captured, fitted with a U.S. Fish and Wildlife metal leg band, measured, assessed for health condition and then released unharmed. Processing of birds is done in compliance with the North American Raptor Banders guide and sanctioned by permit from the U.S. Bird Banding Lab.
